Y ouna mi hines are able to weld pipes and other mttas pig s., such as rails., with cross-sections up to ?.a7AO00 square millhi aterso Each machine has two jaws in which the pipe pieces are held; one of the jaws is fixed, the other one is movable,: Dur- Ing the welding process, the two pipe pieces are alternately i;rou~ht elate together thus their distance is continually varied. The heat thus provoked through varying electrical resistance finally reachc3 the point inhere tires pipes start to scatter oparks. At this moment, the two pieces are brought together by mechanical action and welded, 5 The first Russian order for hair pins from Leuna in 1951 was for the delivery of about 150 pieces. Most of them were of the type with an interior diameter of 120 nn and a total diameter of 1?1 mm. This order was completed in 1951. In January 1952 the Russians gave a new order for 180 hair pine, most of them also of the 120/171 mm ij,pa. Production was begun in March 1952; the order was completed in February 1953 After completion, the hair pins were packed individually into wooden crates and shipped to Russia by rail via Brest Litovsk e 6. No new Russian order for 1953 has c in yet., but there is talk in the works that such an order is pending. There is aloe talk that the welding machine built in 1951 Lo to be shipped to Russia in the near future. Approved For Release 2008/11/21 : CIA-RDP80-0081 OA001200190003-5
